Question

Write the differences between P-wave and T-wave.

Answer 1

Answer:

The differences between P-wave and T-wave in the electrocardiogram( ECG) are:

1. P-wave refers to the activation of the SA node, thereby leading to atrial depolarization whereas the T-wave refers to the ventricular relaxation phase.

2. P-wave is of atrial origin( atrial depolarisation) whereas T-wave is of ventricular origin( ventricular repolarisation).

3. T-wave is slightly more asymmetric and lasts longer as compared to that of the P-wave.

Answer 2

Graphical representation of electrical activity of the heart is known as ECG. To obtained standard ECG, a patient is connected with machine with 3 electrical lead and continuous monitering and multiple lead are placed on chest region.
